An adhesive layer is formed by curing an adhesive composition [I] containing an acrylic resin (X), and has an adhesive strength (α) of not less than 25 N/25 mm, a bending durability (β) of not less than 100,000 times, and a moist heat haze resistance (γ) of not greater than 1.0% as measured under predetermined conditions. The adhesive layer has excellent adhesive strength to adherends, excellent bending durability, and excellent moist heat haze resistance.

A compostable flexible material comprising at least two layers, wherein all of the layers of the compostable flexible material are compostable. The compostable material can be heated in a microwave. A compostable packaging can be made from the compostable flexible material and comprises a compostable reclosable pressure closure.

A compostable flexible material comprising at least two layers, wherein all of the layers of the compostable flexible material are compostable.

A gas barrier film including a substrate film containing a resin, and a gas barrier layer that has oxygen barrier properties and is in contact with at least one surface of the substrate film, a surface of the gas barrier layer has a flat portion, and a plurality of protrusions that protrude from the flat portion. The number of protrusions that satisfy the following formula (1) is 0 to 200 per mm.sup.2, and the number of protrusions that satisfy the following formula (2) is 20 or more per mm.sup.2: d×2≤f (1); and 0.2≤f<d×2 (2), where d represents a thickness (μm) of the gas barrier layer, and f represents a height (μm) of each of the plurality of protrusions.

A release film may exhibit excellent releasability against silicone adhesives and yet reduce the content of fluorine atoms. The release film has a first layer formed from a silicone composition containing a fluorine atom-free curable silicone as a main component on at least one side of a film-shaped substrate, and a second layer containing a component having a fluorine-substituted group on the upper side of the first layer, wherein the first layer has an elastic modulus (F1), as measured using a nanoindenter, of 0.16 GPa or more.

A sheet for heat bonding, having a pre-sintering layer that becomes a sintered layer by being heated, and a component migration prevention layer.

The present disclosure provides adhesive articles that can be removed from surfaces without damage by having reduced or eliminated contribution of a core backing to peel force generated by the adhesive during removal. In some instances, this can be accomplished by a core that loses structural integrity in a direction normal to a plane defined by a major surface. In other instances, the contribution is reduced by compromising the interface between the core and a peelable adhesive layer.

The present invention is directed to a packaging material, more specifically a packaging material having gas and/or moisture barrier properties, wherein the material comprises a barrier material comprising a layer comprising at least 50% of a zinc ionomer, a layer of polyethylene and a layer that forms a gas barrier. The invention is also directed to packaging products using said barrier material. Such products are in particular packages suitable for cosmetics and personal care products.

A system and method for producing a board product made from paper products that have a pre-scored facing in addition to a medium (sometimes called fluting). Conventional corrugated board may feature a cross-corrugated medium and one or more facing that have no score lines that are imprinted (at least prior to assembly with the corrugated medium). Such a conventional board product may be inferior because any score lines that are imprinted will damage the underlying corrugated medium in some manner. A breakdown in the strength of the underlying medium leads to poor precision when the eventual board product is scored, cut, and bent. A lack of precision in folding a board product is known as fishtailing as any articulated portion of the board product may not maintain a precise plane of articulation when bent. Hence, the articulated portion “fishtails” out of alignment. Having precisely located impression lines in register to underlying flutes of a medium ensures correct and precise articulation.

The present disclosure features lens protection systems that include an optically clear anti-fog film which remains on the lens during use, and in some implementations carrier layers that are used to protect the film during shipment and/or assist an end user with applying the anti-fog film to the lens. These systems are suitable for use with a wide variety of optical lenses, for example eyewear, including but not limited to ski goggles, tactical goggles, diving goggles, anti-fog eyewear such as safety glasses, sun glasses, helmet visors (e.g., for football, hockey, or motorcycle helmets), and paintball masks.
